[urq] cooling system

[Ed Kellock]

I wondered about air pockets and thought that would sort itself out. 
The leak this morning was only the 2nd warm/cool cycle since the
repair.

When I removed the thermostat, I flushed the engine very thoroughly
with a garden hose.  Then it sat open for 2 days until I installed the
new hose.  So lots of small passages up higher in the engine may have
drained.  I refilled with coolant and distilled water.

I believe I'll begin with option C right after work today.
